Thorium an overview ScienceDirect Topics

Thorium is nearly three times more abundant than uranium in the Earth's crust, and is present in minerals such as thorite (ThSiO 4), thorianite (ThO 2 + UO 2), and monazite. Thorium is extracted from monazite along with the rare-earth metals. Unlike uranium, information is lacking on the impact of thorium mining and processing.

Steenkampskraal Thorium (Pty) Limited (STL Nuclear)

The mine produced the fuel for the thorium- based nuclear power reactors operating at the time. However, by the late 1960s these reactors were decommissioned as uranium reactors were built, and the market for thorium collapsed. The Steenkampskraal mine closed in 1963, and Monazite & Mineral Ventures was liquidated in 1967. Present day

16 Big Thorium Reactor Pros and Cons Vittana

Thorium ore is generally found in higher concentrations when compared to uranium ore in its respective natural states. That means mining is more efficient and would be potentially safer and less costly. Pit mining is possible with thorium, which eliminates the threat of high radon levels that can sometimes be found in uranium mines.

Uranium and thorium Geoscience Australia

Processing Uranium. Ore from in-situ uranium mines is already in a liquid form as it has been pumped out of the ground. However, ore from open-pit mines is first crushed and mixed with water and then added to large tanks of acid. Because uranium dissolves easily, in solution it becomes separated from other minerals and elements, which remain solid.
